Anyone can learn how to tense up during exercise, that's actually a pretty natural/instinctual response. Learning how to relax/contract/relax in quick succession is what (I've heard) separates the average athlete from the great ones.

I think that also makes good sense. I had no formal instruction with the fluid style, so it feels pretty foreign to me. I feel almost like it takes too much patience... That probably doesn't make much sense.

Do you have a preference Garret? What do you see as advantages or disadvantages of each?
